NC8 - Chambered Exhaust

[Alan Colvin]

Would anyone be interested in purchasing the same stainless chambered exhaust that was produced back in 1985-86 under the C & C Automotive business name? I still have the original tooling and fixtures and would consider producing it again if the demand is there. Maybe some of you guys still have the systems I sold you back then from the late 1980's. Let me know..

Alan,
I think I got one of your systems from D&R in Chicago. Was it 410 stainless, and supposedly made from the original tooling?
I'm happy with the system, just trying to confirm the story I was told.

[Alan Colvin]

All my original systems are easily ID'd, as all of them have a small C inside of a C logo stamping (C & C Automotive) on each component of the system. The stampings were usually at the end of each pipe. The hangers were also stamped with the logo as well.

Oh yeah..they were manufactureed from 409 stanless with a 304 internal tube. The hangers were also zinc plated and used original spiral rivets.

thanks,
Now that you say it, I think they did say 409. I'll look for the mfg stamp.

Hey alan, is that chambered system 2", 2-1/4" or 2-1/2"? I want to put the chambered system on my JL8 crossram car when it's finished but I'll be running headers and would prefer 2-1/2" tubing to help it breath. I realize it won't be 100% stock original, but it will look period correct.

Well, I think the original were 2" (I think), so that is probably what Alan's are also. The chamber diameters are 3", but the inlet/outlets are only 2" (again, I think that's what they are...I am too lazy to measure ours and see!). The worst part is where it flattens under the cross member and right before and right after the last chambers.

I am kind of undecided if we should keep our chambered, or get the "correct" dual into transverse muffler type exhuast. I'm not sure which one would yeild better performance .
